T 0 aZZ whom it may concern.-

Be it known that I, HENRY L. R. WOLF, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Paper Vessels, of whichthe following is a specification, reference being had therein to theaccompanying draw- 1ngs.

This invention relates to paper vessels, and is more particularlyapplicable to that class of paper vessels known as F pails or bucketsordinarily employed as receptacles for oysters, ice-cream, and the likeand formed from a blank which is folded into the desired shape.

The object of the present invention is to provide a bail or handlewhereby the vessel may be properly supported when in use and which willnot tear or disrupt the vessel in its movement relatively to the bodythereof or while the vessel is stored or nested.

To these ends the invention consists in certain'novel features, which Iwill now proceed to describe and will then particularly point out in theclaims.

In the accompanying drawings, Figure 1 is perspective view of a vesselembodying my invention. Fig. 2 is a sectional View taken on the line atw of Fig. 1. Fig. 3 is a perspective view illustrative of the prior art.Fig. 4 is a view similar to Fig. 3, illustrating the nesting of vesselsconstructed in accordance with my invention. Fig. 5 is a detail plansection illustrating the construction of such vessels as are shown inFig. 3. Fig. 6 is a similar view illustrating my improved construction,and Figs. 7 and 8 are respectively a partial elevation and perspectiveview showing the disadvantages of the constructionheretofore employed.

Paper vessels of the character to which my present invention isapplicable are formed from blanks of paper folded into the shapedesired, which is usually that of a truncated pyramid, the vessel beingwider at the top than at the bottom and the lines of fold being exposedat the sides of the vessel and the bail or handle being formed of a wirepivotally connected to the sides of the vessel and serving not only as ahandle, but also as a means for holding the parts of the blank together.

These vessels are usually provided with a top or cover, which is anintegral part of the blank, and such vessels are usually nested orplaced one within the other for storage and shipment, the individualvessels being completed when utilized by folding down the upper portionsof the blank to form the cover and inclose the contents. A usual andwellknown form of such vessels is shown in Fig. 3 of the drawings, whichillustrates this nesting of the boxes.

In said drawings, 1 indicates the vessel, formed from a folded blank,such formation resulting in an exposed free edge between the points 2and 3, as indicated at 4., while 5 represents the wire bail or handle,the ends of which are passed through the holes of the blank, asindicated in detail in Fig. 5, and serving not only as pivotalconnections for the handle, but also as a means for securing the foldsof the blank in position. These boxes are nested for storage andshipment as indicated in Fig. 3, and in this position the bail or handleis turned down so as to lie against the body of the box. It is essentialthat the bail or handle should be turned toward that side of the boxtoward which the outer flaps are folded, as indicated in Fig. 4.

This necessity arises from the fact that if the cause the outermostflaps to slip upon the bail, as indicated in Fig. 3, and thus. permitthe box to be partially opened or unfolded.

This arises from the wedging action of the uppermost boxes inserted inthe lower boxes during the nesting operation. When the bail is turned inthe opposite direction, as shown in Fig. 4:, this slipping of theoutermost side flaps on the bail is obviously prevented. The turning ofthe bail in the direction shown in Fig. 4 presents, however, certaindifficulties. In the first place it will be seen from an inspection ofFigs. 7 and 8 that when the box is to be utilized the turning of thebail upward into the position where it can be used as a handle tends tocause the same to engage with the upperportion of the edges l of theoutermost folds of the box, thereby hindering the proper raising of thebail and causing it to have a tendency to tear or unfold the box.

This arises from the fact that the bail as ordinarily constructedcomprises a cross-piece orhandle proper, 6, and side members 7, whichare bent at their ends, as shown at 8, to pass through the box to formpivots for the hail, the ends being again bent, as shown at 9, intoapproximate parallelism with the side members 7 to prevent the slippingout of the bail. If the parts 7 and 9 are sufficiently close to eachother to tightly embrace the paper of which the box is composed, thenthe outer portions 7 will engage with the edges 4 of the folds, in themanner shown in Figs. 7 and 8 when the bail is raised, and suchengagement is objectionable for the reasons already stated. If, on theother hand, the parts 7 and .9 are not brought close enough together totightly embrace the paper of which the box is com posed, then the parts9 project to a considerable extent into the interior of the box, andwhen the boxes are nested these projecting parts engage with and tearthe paper of the inserted boxes, thereby rendering them leaky and unfitfor use. To overcome these objections, I propose to employ theconstruction shown in detail in Figs. 1, 2, 4, and 6, in which 10represents the box, which is preferably of increasing diameter towardthe top, and which is constructed from a folded blank having outer sideflaps 11, presenting between the points 12 and 13 edges 14, while 15represents the bail com prising a transverse portion 16 and side por=tions 17. These side portions are for the greater portion of theirlength at a distance apart greater than the width of the box at the top,their extremities being bent or deflected inward, as shown at 18, andthen continued for a short distance parallel with the portions 17, butat a less distance from each other, as indicated at 19. These portions19 serve to connect the portions 17 with the pivotal portions 20 of thebail, which are bent at right angles to the portions 19 and pass throughthe paper of which the box is composed. The ends of the bail, asindicated at 21, are again bent at rightangles, so as to be parallel tothe portions 19, the parts 19 and 21 bearing against the outer and innersides of the box, respectively, and closely embracing the same, so thatthe parts 21 he close to the inner wall of the box. The parts 19 are ofa length less than the distance from the pivotal portions 20 to theedges 14 of the outerflaps of the box. It results from this constructionthat the ends of the bail embrace and hold the folded paper walls of thebox for a comparatively short distance, so that the frictional contactbetween the ends of the bail and the box is not sufficient to materiallyimpede the swinging up of the bail into the position which it assumeswhen in use.

If it were not for the bending or deflecting outward of the sideportions of the bail, as indicated at 18, then these side portions wouldhave too extended a contact with the waste outer walls of thebox, andthe resulting fric tion wouldimpede the motion of the bail. If in orderto avoid this friction the inner ends of the bail were not brought intoclose parallelism with the outer side portions thereof, then said innerends would project to an ex cessive extent, as indicated at 9 in Fig. 5.Moreover, my improved construction is such that the portions 17 of thebail do not come into contact .with the edges 14 of the outer flaps 0fthe box when the bail is brought into vertical position, so that thebail may be readily swung up into operative position without meetingresistance and without damaging or loosening the box. Ihave thusprovided each box with a bail which will properly accomplish itsfunctions when the box is in use and which when the boxes are nestedwill not tear or damage the adjacent boxes, since the parts 21 lie closeto the inner side walls of the box in such a position as to permit theready insertion and removal of other boxes. Moreover, my improvedconstruction permits the turning down of the bail on that side of thebox which will pre vent the opening up of the box in nesting and at thesame time avoids the objections heretofore pointed out as attendant uponthe turning down of the bail on this side and arising from the tendencyof the bail to engage the free edges of the outer folds of the box whenturned up into position for use.

While my invention is particularly adapted for use in connection withpails of the char-' acter described, I do not wish to be under stood aslimiting its application to such pails, as it is obviously capable of awider range of use. It is obvious that when my improvement is employedwith a vessel pyramidal in form and widest at its top the out warddeflection of the bail at each side enables the sides of the bail to befastened to the box below its top, where it is narrower than at the top,while at the same time preventing contact between the bail and theupperportion of the pail immediately adjacent to the top, thus avoidingexcessive friction at this point. Moreover, the sides of the bail may bebrought into parallelism as to their wider portions, thus avoiding anexcessive width of bail at its top. It will thus be seen that myimprovement is of special advantage in connection with vessels ofpyramidal form having an increasing width toward the top.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The combination, with -a folded paper vessel having side flaps withexposed edges, of a bail or handle, the ends whereof pass through theside walls of the vessel to form pivots, the ends being bent up againstthe inside of the vessel, those portions of the bail adjacent to thepivots being brought into parallelism to closely embrace the walls ofthe vessel, and the remaining parts of the side portions of the bailbeginning below the rim IIO of the vessel being bent or deflectedoutwardly so as to be free from contact with the vessel, substantiallyas described.

2. The combination, with a folded paper vessel of increasing Widthtoward the top and provided with side flaps having exposed edges, of abail or handle, the ends whereof pass through the side walls of thevessel to form pivots, the ends being bent up against the inside of thevessel, those portions of the bail adjacent to the pivots being broughtinto parallelism to closely embrace the walls of the vessel, and theremaining parts of the side portions of the bail beginning below the rimof the vessel being bent or deflected outwardly so as to be free fromcontact with the vessel, substantially as described.

3. The combination, with a foldedpaper vessel having side flaps withexposed edges, of a bail or handle, the ends whereof pass through theside walls of the vessel to form pivots, the ends being bent up againstthe in side of the vessel, those portions of the bail adjacent to thepivots being brought into parallelism to closely embrace the walls ofthe vessel, those parts of the outer side portions of the bail from thepivots toward the han= dle portion which are thus brought into contactwith the outer side walls of the vessel being of less length than thedistance from the pivots to the exposed edges of the side flaps, and theremaining parts of the side portions of the bail beginning below the rimof the vessel being bent or deflected outwardly so as to be free fromcontact with the vessel, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.
